' CORPORATION OF INDIANA ADJUSTABLE ros'r BRACKET Original application filed February 13,1924, Serial No..692,574. Divided andthis application filed 'May 12, 1927. Seria1.No.190,92 4.

This invention relates to brackets of that general class which are adapted to be clamped to a post for use in the construction of gas tanks, oil tanks, and other constructions or installations where a bracket of this general character is needed. V

The object of the invention is to provide a simple, strong, and durable foldable post bracket of improved construction provided with novel means for attaching it to the post and holding it in any desired position thereon, without possibility of accidental slippage or of wabbling, and adaptability for quick and easy adjustment or removal.

The invention also comprehends theimproved clamping or fastening device which is used in connection with the bracket.

' The bracket and the clamping or fasteningdevices thereof are ,so constructed and arranged that the bracket may be applied to any post of the usual sizes employed in construction work.

The bracket is so constructed that it may be folded into compact arrangement so as to be readily carried about without occupying much space.

In the following specification and the accompanying drawings there is setforth one embodiment of the invention. It will be understood, however, that modifications may be resorted to within the spirit and scope of the invention.

In the accompanying drawings: 7

Figure 1, is a perspective view showing the bracket applied to a post, dotted lines representing the manner in which a plank may be laid on the bracket;

Fig. 2, is a detail vertical section through the arm and brace of the bracket, showing the adaptability of the clamps for adjustment; a

Fig. 3, is a detail cross section on the line 33, Fig. 2; and 7 Fig. 4, is a detail perspective view of one of the clamps, shown alone.

The fragment of a post such as commonly used in the construction of gas tanks, oil

ner of use of the bracket which is shown .ap'- plied thereto,

' The bracket is of metal and is complete and self-contained, ready for adjustment to. any post such asthat shown atl. The bracket has an arm 2- and a brace 3 whichare of angleiron construction for purposes i of strength, the two being jointed together on I the screw threaded boltfl. .When the brack- 'et is in use, the arm 2 is'adapted to support a plank, shown in dotted lines at 5, it being understood that the-plank runs from a bracknut the arm and brace may be securely con nected to the: post 1.

To provide for a wide bearing on the shank 6. for the purpose of preventing canting of the clamp bolts, the bearing plates 10 and Y1 1 are-provided on the-arm 2 and the bearing plate 12 is securedto the brace 3. Rivets 13 are preferably employed for fastening the bearing plates 10,11,12. Q i l The shank of the r arm 2 need notbe adjusted in the direction of the lengthof the arm; If it is desired to provide for adjustment of the shank of'the left hand bolt for the arm 2, the bearing plate 12 is elongated as shown at 14 and there is' provided an elongated hole or slot 15 in the vertical web of the arm 2. Thus, the arm is rendered adaptable for application to postsl of different sizes. V

I The clamp bolts which secure the brace 3 are preferably adjustable to adapt them to posts of different sizes, hence both bearing plates 12 are elongated. An elongated slot 15 in the vertical web of the brace 3 is provided for adjustment of the right hand clamp bolt. The left hand clamp bolt of the brace 3 ight hand bolt for .thei may be insertedin any one of the series of holes 16 in the vertical web of. brace 3. In all instances,the provision of the bearing plates prevents twisting or canting of the bolts; andthe edges of the bearing plates, together With the edges of the arm Q and brace 3, afford a. suitably Wide bearing for. the nuts 9 so that the clamp bolts may be turned up very'tightly, causing the arm and 10 brace to be securely held against the post.

Whereas provision is shown for adjustment of the bolts in the direction of the length of the arm and brace, it is to be understood that, =unless specifiedin the claim, the invention is not limited to the provision of means affording this adjustment. V

The clamp bolts being disposed transversely of the arm and brace and there being two in each instance, the bracket will support very heavy Weights as the bolts cannot-give wa unless they are completely sheared off; an because the Weight supported by the V bracketis applied crosswise of the bolts, in l stead of lengthwise thereof, therefis no danger t of the threads of the bolts being stripped by the weight.

What is claimed is: r

In a bracket foruse on wooden posts, the combination with an arm of angle-iron, of a brace therefor which is of angle-iron and means for independently securing the arm and the brace to the post, comprising in one instance screw-threaded bolts Whose shanks pass through'one web of thebrace and are spaced 'apartto adapt them to lie on opposite sides of thepost, and in the'other instance screw-threaded bolts whose shanks pass through one web of the arm, and are spaced apart to adaptthem to lie on opposite sides of the post, said screw -threaded bolts each having a post-penetrating point at one end and a nut at 'the'other end, bearing plates being secured 'to the webs. of the arm and 1 brace, respectively, and serving as mountings for the shanks oi the screw bolts and as abutments for the nuts aforesaid, a a
